I've never done it before myself, but here's how I would go about doing it;

If you're simply after a Circular style of destruction, then what you want for your terrain ( the image ) is just a filled circle routine.

Simply fill the circle with whatever colour is your transparent colour ( default is black ), and you're done!

If you want something more random ( for what, or what kind, I don't have a clue ), then do a combination of filled circles

Jess.

Check out my compo entry in the showcase called Tankoids.

http://www.thegamecreators.com/?gf=2004compo_view&i=64

It comes with the source.

It's very very fast detructable terrain code, it works like this:

Have an array - Floor(4000) - that contains the starting floor height for the level (assuming level is 4000 pixels wide).

Then you need another array that contains the positions of the holes. Then to check for collision check whether it is under the ground and whether it is within 100 pixels or whatever of the holes.

The actual holes are just circled coloured the same as the sky.

Have a look at my Lemmings remake:

http://www.geocities.com/avanmadisen/projects/pages/lemmings.html

The landscape handling is almost identical in it's final effect to both lemmings and worms. The source code wouldn't help you much because my code never looks anything like anyone elses, but I'm thinking of writing a tutorial on my method of doing it, so if you want I'll do it soon.

I don't suffer from insanity:

I enjoy every minute of it!

memblocks are probably the way to go... You could write a collision system with that as well.
